Title: Custom 10mm AR15 Uppers from RMW EXTREME
Post by: REDLINE on August 04 2013 05:48:46 PM MDT
Just came across these custom 10mm AR15 uppers.  The website (http://www.rmwxtreme.com/ (http://www.rmwxtreme.com/)) is under construction but shows an email address for more info.

Barrel is 10.5".  Seems they run around $800.00.

Here's the best YouTube video I could find (though it's a full-auto set-up);  http://www.youtube.com/watch?v=Ro5_r3_vTZw (http://www.youtube.com/watch?v=Ro5_r3_vTZw)

Anyway, just wanted to throw it out there for anyone who may be interested.

Deadly.

I will take one to go with a 16 inch barrel.

That was a lot $$ in 10mm ammo he just blew through in 2 seconds,  :P

Not to bad if you reload, which Ron does.

I thought Olympic Arms has offered a 10mm Upper for awhile ?

Are they gas or blowback operated?

The Olympic is blowback, chances are the other one is too.

Nope.  The RMW upper is gas operated & that's its major advantage.  Ron has been working for years with gas operated pistol caliber uppers.  10mm, .40, .45, .357 sig, and a few others.  Even 9mm, though that one requires hot loads to work properly.

I contacted them a while back, maybe a year ago, about the uppers.  He told me it was about 6 months lead time and $800-$900 for a 10mm upper.
I haven't ordered one, yet.

Where do you get a lower that takes Glock magazines?

I want to order one of these. Never owned an AR before. I think the 16 " barrel is what I want. Owners and other AR guys, is this the right choice?

I am thinking about building one of these in a 10-12" pistol version?! Yes, no!
